The issue is the 8 minutes with the ref stood with his finger in his ear and then 5 minutes added time in a first half with no injuries at all. Ball goes in the net, do you celebrate or wait two minutes for confirmation? It'll kill the game.

In no other game would that Lamela goal have been ruled out, yet the ref never even looked at it, took the anonymous VAR official saying no goal as read when even after detailed slow motion analysis there was no real indication why. Huh??

Is there no equivalent of the cricket "soft signal" (I think it is out so any doubt that is the call) or the rugby "any reason I cannot give a try?" to refer a dubious one upstairs. In tennis there is a call of in or out, then the affected player can ask for a referral, and the game is inherently stop start between plays. American football is stop start anyway so going off for a ruling on all scoring plays isn't the same issue.
